Description

Technical Field

[0001] This application relates to thermoplastic elastomer (TPE) processing technology, and more specifically to a crushing device for processing thermoplastic elastomer (TPE). Background Technology

[0002] With the rapid development of modern industry, thermoplastic elastomers (TPEs) have gained widespread application in numerous fields due to their unique advantages, such as combining the high elasticity, aging resistance, and oil resistance of traditional vulcanized rubber with the easy processing and diverse processing methods of ordinary plastics. In the automotive manufacturing industry, they are used to produce automotive seals, interior mats, and door seals; in the electronics industry, they are used to manufacture wire and cable sheaths, electronic device housings, and other components; and in the consumer goods sector, they are commonly used to make handles, cup lids, and cup holders.

[0003] In the TPE processing, the crushing stage is crucial. On the one hand, sprues and scraps generated during production need to be crushed and reused to reduce production costs and improve resource utilization. On the other hand, to meet the requirements of different processing techniques and product performance, TPE raw materials sometimes need to be crushed to a specific particle size. However, existing crushing equipment has many problems when processing TPE materials.

[0004] For example, Chinese Patent CN216682888U discloses a crushing device for processing thermoplastic elastomer (TPE), including a housing. A secondary housing is fixedly installed at the upper end of the housing. A filter element is provided at the upper end of the secondary housing, and a material limiting element is provided inside the secondary housing. A material guiding element is provided at the lower end of the filter element, and the material guiding element is located inside the housing. The crushing device body is located inside the housing, and the material guiding element is located directly above the crushing device body. A discharge port is provided on the front of the housing. This crushing device uses the above structure, where a motor drives a first screw inside the housing to rotate, causing one end of a sliding plate outside the first screw to slide inside the housing. Simultaneously, a guide head is installed in the middle of the sliding plate via a fixed block. The upper end of the guide head is connected to a cloth cylinder, allowing the lower end of the guide head to evenly feed material into the middle of the rollers of the crushing device body for crushing.

[0005] The aforementioned crushing equipment is used in the melting and plasticizing stages and cannot crush waste and scrap materials in TPE processing. Furthermore, similar crushing equipment in the prior art crushes waste and scrap materials by combining a rotating auger and a perforated plate cutter, which results in poor crushing efficiency and adhesion between particles. Based on this, we designed a crushing equipment for thermoplastic elastomer (TPE) processing. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a crushing equipment for processing thermoplastic elastomer (TPE), which has the advantages of high crushing efficiency, good crushing effect and low equipment cost.

[0014] In a preferred embodiment: the surfaces of the lower roller and the upper roller are provided with conical protrusions, which can increase the friction between the lower roller, the upper roller and the TPE material, making it easier to feed the material into the crushing box.

[0019] In a preferred embodiment: the outer sides of the first sprocket and the second sprocket are provided with outer covers.

[0020] Compared with the prior art, this application has the following beneficial effects:

[0021] 1. This application uses a drive motor to simultaneously drive the crushing blade and the pressing mechanism, so that the crushing equipment crushes and cuts the material while pressing the TPE material.

[0023] 3. This application uses the relative rotation between the lower roller and the upper roller to compress and neatly transport the TPE material in the feed hopper into the crushing box, thereby facilitating the crushing blade to cut and ensuring the cutting effect.

[0034] A pulverizing device for processing thermoplastic elastomer (TPE), such as Figure 1-5 As shown, it includes:

[0035] The crushing box 2 has a feed hopper 4 on one side and a discharge hopper 13 on the other side; the crushing box 2 is equipped with a crushing blade 16 inside for crushing TPE material.

[0036] Support frame 1, with casters at the lower end and the upper end of support frame 1 used to support crushing box 2;

[0037] The pressing mechanism 3 is located on the side of the feed hopper 4 near the crushing box 2, and is used to neatly press the TPE material into the crushing box 2.

[0038] The drive mechanism is located at the lower part of the support frame 1 and is used to simultaneously drive the crushing blade 16 and the pressing mechanism 3 inside the crushing box 2 to crush TPE material.

[0039] In one specific embodiment, such as Figure 4As shown, the shredder 16 includes a blade holder 161, which is cross-shaped. Blades 162 are mounted at each of the four ends of the blade holder 161. A drive shaft 163 is mounted in the middle of the blade holder 161. Both ends of the drive shaft 163 pass through the shredder 2 and are rotatably mounted on the upper end of the support frame 1. The drive mechanism drives the drive shaft 163 to rotate, which in turn drives the blade holder 161 and blades 162 to rotate, thereby cutting and shredding the TPE material entering the shredder 2.

[0040] In one specific embodiment, such as Figure 5 As shown, the pressing mechanism 3 includes two support plates 201 symmetrically arranged on both sides of the upper end of the support frame 1, and a lower roller 202 and an upper roller 203 arranged between the two support plates 201. The lower roller 202 has a lower roller shaft 204 in the middle, and the two ends of the lower roller shaft 204 are rotatably connected to the lower part of the support plates 201 on both sides. The upper roller 203 has an upper roller shaft 205 in the middle, and the two ends of the upper roller shaft 205 are rotatably connected to the upper part of the support plates 201 on both sides. By driving the lower roller shaft 204 and the upper roller shaft 205 to rotate through the driving mechanism, the lower roller 202 and the upper roller 203 will rotate relative to each other, thereby clamping the TPE material in the feed hopper 4 and conveying it into the crushing box 2.

[0041] Based on the above embodiments, the surfaces of both the lower roller 202 and the upper roller 203 are provided with conical protrusions, which can increase the friction between the lower roller 202, the upper roller 203 and the TPE material, making it easier to feed the material into the crushing box 2.

[0042] In one specific embodiment, such as Figure 1-3 As shown, the drive mechanism includes a drive motor 5, pulley 7, pulley 8, pulley 9, gear 10, gear 21, sprocket 15, and sprocket 217. The drive motor 5 is mounted on the lower part of the support frame 1, and pulley 7 is mounted on the output end of the drive motor 5. Pulley 8 is mounted on one end of the drive shaft 163, and pulley 9 has a shaft 18 in the middle, which is mounted on the upper part of the support frame 1 via a bearing seat. Pulley 7 and pulley 8... 8. Pulley 2 and Pulley 3 are both connected by belt 6; Gear 10 is installed on the side of shaft 18 of Pulley 3 near Pulley 3 9, and Gear 21 is installed on one end of shaft 204 of lower roller, and gear 10 and gear 21 mesh with each other; Sprocket 15 is installed on the end of shaft 18 of Pulley 3 away from Pulley 3 9, and sprocket 217 is located on one end of shaft 205 of upper roller, and sprocket 15 and sprocket 217 are connected by chain 14.

[0043] Specifically, the drive motor 5 drives pulley 7, pulley 8, and pulley 9 to rotate. Pulley 7 drives the blade holder 161 and blade 162 to rotate, thus crushing the TPE material. Pulley 9 simultaneously drives gear 10 and sprocket 15 to rotate. Gear 10 drives gear 21 and lower roller shaft 204 to rotate. Sprocket 15 drives sprocket 27 and upper roller shaft 205 to rotate, thereby simultaneously driving the lower roller 202 and upper roller 203 to rotate relative to each other, clamping the TPE material and conveying it into the crushing box 2.

[0044] Based on the above embodiments, both sprocket 15 and sprocket 2 are provided with outer covers 12 on their outer sides. The outer covers 12 serve as safety protection and prevent dust and debris from affecting the operation of the sprockets.

[0045] The working process and beneficial effects of this utility model are as follows:

[0046] During operation, the drive motor 5 is started, which drives pulley 7, pulley 8, and pulley 9 to rotate, which in turn drives the blade 162, lower roller 202, and upper roller 203 to rotate simultaneously. The TPE material to be crushed is placed into the feed hopper 4. The TPE material slides downward under the action of gravity. When it reaches the position of the lower roller 202 and upper roller 203, it is drawn between the lower roller 202 and upper roller 203 by the relative rotation of the lower roller 202 and upper roller 203 and squeezed, so that the material neatly enters the inlet of the crushing box 2. At this time, the rapid rotation of the blade 162 cuts the TPE material into fine particles, which are then discharged from the discharge hopper 13 of the crushing box 2, completing the crushing of the TPE material.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
